The Aga Khan Award for Architecture was established by His Highness the Aga Khan in 1977 to identify and encourage excellence in architecture in societies where Muslims have a significant presence. The Award is given every three years and recognises all types of building projects that affect today's built environment. The book presents a shortlist of 19 projects including the winners. What these projects have in common is a commitment to design excellence despite constraints of budget, resources, climate, technology, and politics. They share this commitment as one of the necessary tools for societal betterment.
